I used a mover a few years ago they actually work pretty good however at that time the weight limit wasn't up to what I needed when I was running xxxl cool hood right now in my 4x8 tent I'm running 2 600 hps in air cooled hoods temps are usually always between 74-80 f my last grow room that I grew the plant that was in bom was a 6x7x7 with ac I loved it but had to move so had to go back to a tent I want to give the mover another go but the one I want is pricey almost 500 bucks!but it would pay for itself with the savings on electric
